  2. 1. Nanoscale Reaction Systems

    Author : Karin Fromell; Karin Caldwell; Francesco Dondi; Uppsala universitet; []
    Keywords : Life sciences and physical sciences; nanoparticles; Sedimentation Field-Flow Fractionation; bioaffinity; multilayered functionalization; protein attachment; diagnostics; bioluminescence; NATURVETENSKAP;

    Abstract : The work presented in this thesis describes the use of polystyrene nanoparticles as model surfaces for bioanalytical work. Nanoparticles constitute convenient platforms for the attachment of bioactive agents, and receptor coated particles offer high local concentration of binding sites for specific ligands with minimal steric hindrance.

  4. 2. Graphite oxides for preparation of graphene related materials : structure, chemical modification and hydrogen storage properties

    Author : Alexey Klechikov; Alexandr Talyzin; Tamás Szabó; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Graphite oxide; graphene oxide; hydrogen storage; nanomaterials; adsorption; surface area; pore volume; Materials Science; materialvetenskap;

    Abstract : Carbon materials have been studied for hydrogen storage for decades, but they showed too low capacity at ambient temperature compared to target values for practical applications. This thesis includes two parts. First one is fundamental study of graphite oxides (GO) structure and properties. READ MORE

  5. 3. Properties and applications of materials based on graphite oxide

    Author : Andreas Nordenström; Aleksandr V. Talyzin; Thomas Wågberg; Andrey Turchanin; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Graphene; Graphite Oxide; Graphene Oxide; Swelling; Phase Transition; Intercalation; Activated Graphene; Activated Carbon; Supercapacitors; Neutron Reflectometry;

    Abstract : Graphite oxide (GO) is a hydrophilic, layered material prepared by oxidation of graphite. In the first part of this thesis, we studied materials produced from GO by intercalation and functionalization. The second part of the thesis was focused on supercapacitor applications of high surface area carbons prepared from GO using chemical activation. READ MORE
